For the first time on interstellar travel, alone in the vast cosmic starry sky, Ye Qiuli had already been fully prepared for the infinite risks contained in it, everything was based on safety, and in the case of insufficient self-cultivation, he relied more and more on the assistance of scientific and technological means, and did his best to ensure that the spacecraft operated without errors.

And the final result also completely proves that his method is indeed very effective, so far, after comparing the star map in the spaceship brain database with the star map recorded in his hand, he has not found that his spaceship is flying in the wrong direction.

Indeed, in the process of exploring the universe, the speed, range, and safety of the spacecraft, and the changes in the psychological and physiological state of the astronauts are not the most dangerous problems, but the most dangerous problem is to get the wrong direction and get lost in the vast starry sky.

In such a small space as the earth, getting lost can make people easily lose their lives, not to mention the vast and boundless starry sky of the universe. Once you get lost in the vast space where you can't distinguish between the front and back, the left and right, up and down, it is definitely an extremely terrifying thing, and I am afraid that the final result can only be to sit still, and want to find the right path again, the probability is definitely less than the possibility of being hit by a meteor falling from the sky on the main road.

And Ye Qiu's practice of releasing a satellite every time he flies to maintain a direct connection with the Earth is to leave a clear origin and a series of clear marks in his interstellar journey. In that case, figuratively speaking, it is actually equivalent to tying a kite string to a kite flying in the sky, so that it is always under control, not afraid of the danger of getting lost and getting rid of it.

Although Ye Qiuli had previously found a few special star markers for cultivators when he was checking the Liuyun Immortal Ring, and found a simple teleportation route map for leaving the earth marked by Lu Yan in one of the treasure-level superb star markers, and he himself went to the ruins of the remaining teleportation array on the earth to check and confirm that it was completely operational, and according to the direction and distance marked by Lu Yan, he could indeed find the teleportation array he needed. But being prepared is always a commendable thing, and it certainly doesn't hurt to be a little more prepared.

After all, his cultivation at this time is only in the early stage of the Yuan Infant, far from reaching the distraction period where he can move between planets alone with his own strength, especially the gap in divine consciousness is very huge, and he has no ability to lock on to a strange planet a few light years away, if he is not fully prepared, he will fly around the universe like a headless fly, and if he is not careful, he may lose his target and lose his direction.

In addition to not being able to lock on to the target planet, there is another thing that particularly worries Ye Qiuli, that is, he is taking a spaceship to shuttle through space at this time, the flight speed is slow and takes a long time, he simply does not have enough energy to keep an eye on the target from time to time, and personally pilot the spaceship to fly, he can only set a flight direction and let the spacecraft move forward automatically, and he compares and adjusts the flight route every once in a while to ensure that he does not fly in the wrong direction.

It's just that in this way, although it does save a lot of time and effort, the hidden risks are also infinitely increased. You must know that in the vast universe, it can really be said that the difference is by a fraction of a centimeter, and it is a mistake of thousands of miles! Even if it is only a small error of one degree from the original route, after magnifying to a distance of several light years, we do not know where it will be, and we will immediately lose our way completely.

Interstellar voyage, the vast and incomparable cosmic starry sky is the biggest enemy!

It is precisely out of great vigilance against this hidden risk that after leaving the solar system, Ye Qiuli has always been very cautious, and he did not dare to be negligent at all, for fear that he would accidentally fly in the wrong direction and lose his position. This is the trouble of not having enough strength, even if he has the star and star map dedicated to cultivators in his hand and knows the route and direction of progress, but his ability is insufficient, there is still a huge risk of losing his way.

This is also the key reason why the middle and low-level cultivators in the cultivation realm never dare to leave the teleportation array and run to other isolated planets when they go out to travel. They kept an eye on the teleportation array, in addition to facilitating their movements, the more important reason was to prevent them from getting lost in the infinite starry sky.

In this case, it is like getting lost in the vast primeval jungle, even if the person has the most detailed map of the earth's coordinates, but there is no way to judge his specific coordinates, and he cannot find out his relative position, it is still useless. Unless the lost man can find a landmark area with clear coordinates to revitalize the entire map system, he will basically have to wander around in the dense forest where he can't distinguish between things and things.

For all cultivators, the teleportation array is the most typical coordinate marker, as long as they rely on a complete teleportation array, they can easily identify the exact location where they are, and then comprehensively understand the detailed coordinate map of most of the life planets in the entire cultivation realm.

It's like if you find a place where people gather in towns, villages, and other places on the planet, you're sure to find your way home. Because the coordinates of those places are already relatively clear, it is possible to find larger and more significant high-level coordinates through them, and at that time, as long as the route is planned, there will be no difficulty in reaching the original goal. Once you're in the civilized world, there's always a way to find a route.

At this time, the situation that Ye Qiuli encountered was equivalent to holding a road map of action in his hand (the teleportation route map outlined by Lu Yan), but he needed to start from another city (such as the teleportation array in the Alpha Centauri), but the road that originally connected that city and the city he was now was destroyed (the teleportation array on the earth had been completely destroyed, and there was no way to teleport through it), and now he only had information such as the location and distance of that city, and if he wanted to enter it, he had to pass through a barren field (4, 5 light-years cosmic starry sky), and this barren wilderness is the kind that is easy to get lost, and you can get lost in it if you are not careful.

For such a situation, Ye Qiuli could have waited until the conditions were ripe to fly over directly, which was safe and fast. It's just that he doesn't want to waste time waiting for the conditions to be ripe, and he wants to leave early and arrive early. So, after making only a few simple preparations, he set out on his own journey, ready to walk through the barren wilderness and reach the city where the course of action began as quickly as possible.

In this way, although he has a map indicating the relative position of the departure city and the destination city, there are no clear coordinates on the vast wilderness between the two cities, and in order to ensure that he does not go in the wrong direction, he must often stop and use the positioning tool in his hand to mark his position, so that he is always on the straight line connecting the two cities to prevent him from going on a fork in the road. At the same time, in order to have a chance to save and make up for mistakes, he often leaves marks behind him to facilitate his return and start again.

It is precisely for this reason that in the process of going to the Alpha Centauri star system, Ye Qiuli will pause every time he flies, while referring to the earth azimuth map marked by Lu Yan in the star marker, and on the other hand, referring to the galaxy star map recorded by the earth astronomical community, carefully comparing the specific direction and distance he is in, to ensure that his flight direction is not wrong.

At the same time, according to the results obtained by his actual exploration, he marked all the information of all the planets encountered along the way into the spacecraft's brain database and the star markers in his hands, hoping to establish a complete interstellar stereoscopic map with the earth as the initial coordinates, and enrich and improve it as soon as possible to connect with the original star map in the star mark, so as to form a larger and more complete giant stereoscopic star map covering the entire solar system.

After all, when geoscientists use space telescopes to observe the starry sky outside the solar system, except for those stars that can emit bright light, which can be easily observed, those planets that do not emit light, moons and other planets are difficult to find, let alone observed. As a result, the three-dimensional map of the Milky Way created by them is actually quite incomplete, and most of the planets have not been observed and recorded.

Such a star map may not be a big problem for ordinary people, because they have no chance to wander around space at all, and they don't need an interstellar map at all. However, this kind of incomplete star map was quite a problem in Ye Qiuli's hands, because the planets he wanted to look for that might have teleportation arrays or even life were planets that could not be observed by this ordinary method, such as planets or moons, which did not shine.

Therefore, if he wants to make the galaxy map in his hand work to the greatest extent and most accurate, Ye Qiuli must also spend a lot of effort to supplement it, just having a detailed map of the solar system, plus some large and general star location maps, can not meet his needs at all.

It's like cutting out a very small piece from a very large map, with only a few names of places you know marked on it, and if you look at it by a stranger, I'm afraid no one knows which map it is cut from, and it doesn't match any big map for the time being. If you want it to be able to function in a relatively large area, you can only use it as a starting point to keep exploring outwards and constantly replenishing and improving it, until it is expanded to a sufficient range, and it can naturally form one or several iconic locations that can be connected with other large maps.

Here's a more detailed example: a map of a small village on the edge of the Yellow River, for example, no one knows exactly where it is, but it expands along the perimeter of the village, and one day it will be possible to include the entire Yellow River. At that time, others can naturally see at a glance that it is the Yellow River, because the curve of the "several" figure is too eye-catching, and at that time, this map, which no one knows where it is, can naturally be connected with the world map, so as to play its clearest indication role.
